Original scientific paper published in a classical journal covering the field of nuclear materials presents our results on removal of carbon deposits from fusion devices. To the best of our knowledge it is the first report worldwide on controlling the removal rate. The reaction probabilities were calculated from measured flux of radicals and corresponding thickness of the deposit.

For certain values of the plasma parameters the Bohm criterion is triple valued. Three methods to select the correct Bohm velocity are compared. Our main contribution in this work is the method which is based on the numerical solution of the Poisson equation. The transition from the low to the high Bohm velocity occurs at the parameters where the numerically found space charge density profile indicates the formation of a double layer in the sheath. These parameters are always identical to the parameters found with the maximum positive ion flux method, when the latter can be applied.
